Only live matches earn points; dead rubbers earn no points. If a player does not compete in the singles of one or more rounds he will receive points from the previous round when playing singles at the next tie. This last rule also applies for playing in doubles matches.
1 A player who wins a singles rubber in the first day of the tie is awarded 5 points, whereas a singles rubber win in tie's last day grants 10 points for a total of 15 available points.
2 For the first round only, any player who competes in a live rubber, without a win, receives 10 ranking points for participation.
3 Team bonus awarded to a singles player who wins 7 live matches in a calendar year and his team wins the competition.
4 Performance bonus awarded to a singles player who wins 8 live matches in a calendar year. In this case, no Team bonus is awarded.
5 Team bonus awarded to an unchanged doubles team who wins 4 matches in a calendar year and his team wins the competition.
